Transmission Range
22. Specifications
Outdoor data
The transmission distance from the thermo-hygro sensor to the base station in
open space under optimum conditions is 100ft. Although the signal
transmission may travel though solid surfaces or objects, the following points
should be avoided if possible:
Transmission Distance in Open Field
:
100ft max.
Temperature Range
:
-
21.8°F to +157.8°F (show OFL”
if outside range)
Resolution :
0.2°F
Measuring Range Rel. Humidity
:
20% to 95% (if the relative
humidity is less than 20% or
greater than 95%, it will display
19% or 96%)
•
High frequency interferences of any kind.
•
High densities of trees.
•
Broadband interferences in municipal areas can reach levels reducing the
signal/noise ratio over the entire frequency band, thus also reducing the
transmission distance.
Rain Volume Display
:
0 to 39.37 inches (1h and 24h
rainfall)
•
Devices working close by (example a neighbor’s house) may also
influence reception.
0 to 98.38 inches (Total rainfall)
Resolution :
0.1mm
•
Poorly shielded PCs can cause interferences that will reduce or in some
cases stop reception
Wind Speed
:
0 to 111.8 mph
Resolution :
0.1
mph
•
The transmitter and receiver should not be mounted on metal surfaces as
this will reduce transmission range.

Cleaning and Maintenance
Using 433MHz wireless data transmission:
•
Clean the housing and screen of the base station only with a soft damp
cloth. Do not use abrasives or solvents.
Measuring interval
thermo-hygro sensor
:
32 sec (if wind factor>22.36
mph) or 128sec (if wind factor
•
Ensure that the rain sensor does not collect leaves or other dirt by
checking the funnel for blockages every now and then. Also clean the
seesaw of the sensor with a damp cloth and check by lightly tapping with
your finger that it can move freely from side to side.
< 22.36mph) 10 minutes (if the
base station fails to receive any
data after 5 attempts in a row, all
outdoor data readings will
display “---“, except for the rain
value)
•
Do
not
clean the funnel with the bottom half of the rain sensor attached
nor the bottom part itself under running water. This may bear the danger
of water entering the unit’s inner parts and cause damages.
•
Do not immerse the base station in water.
•
Should there be damage to this product, please do not attempt to make
any repairs. Please take this unit to a qualified technician. Opening or
improper handling of the units will invalidate any guarantee.
